SHOE-STITCHER ATTACHMENT.

Application filed February 17, 1920.

T 0 all whom it may concern:

Be it known that I, CHARLEY J. Srmvonn, a citizen of the United States, residing at Osceola, in the county of Clarke, State of Iowa, have invented certain new and useful Improvements in Shoe-Stitcher Attach merits; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use the same. I

This invention relates to the class of boot and shoe making and has reference more particularly to stitching and channeling machines adapted to produce an open cut or channel in an insole or welt, orsole and to stitch or sew the same together, the invention embodying an attachment of the form of a shield to cover the channel cutter when stitchingrubber soles on shoes, at which time it is not desired to have the cutter in operatiou.

A further object of the invention is to provide an attachment for the purposes specified which is particularly adapted for a straight needle shoe stitcher, the improvement consisting of a shield for covering the channel cutter when stitching rubber soles on shoes, so as to save time by obviating the necessity of taking out the screws and removing the channel cutter in order to permit the attachment of a blank plate in the place thereof, the construction of the attachment being such as to permit the stitching operation to be carried on with equal facility and to be. instantly put on or taken ofii.

A further object of the invention consists in the construction of a shield attachment having a lip to catch under the needle plate and to fit over the channel cutter and means by which it may be readily and securely attached or removed with facility so as not to impede the stitching operation, but on the other hand, to greatly facilitate the stitching of rubber soles on shoes.

With the above objects and others in view as will appear as the specification proceeds, the invention comprises certain novel combinations and arrangements of parts as will be hereinafter more particularly pointed out and claimed.

Reference is had to the accompanying drawings forming a part of this application,

Specification of Letters Patent.

Fatcnted June 28, 1921.

Serial No. 359,215.

wherein like characters designate corregonding parts throughout the several views, in which- Figure 1 is an elevationshowing part of a shoe stitching machine provided with a needle plate and channel cutter, having the shield attachment applied thereto,

Fig. 2 is a view at right angles to Fig. 1,

Fig. 3 is a plan view of the attachment, and

Fig. 4: is a perspective view thereof partly in section.

Referring to the drawings indetail, there is shown a portion of a stitching and channeling machine preferably of the straight needle type, which includes the table 10 having the overhanging frame portion 11 carrying the pressure foot and stitching mechanism indicated at 12. The needle cap is indicated at 13 and the needle plate at 14c, while the channel cutter is indicated at 15. The channel cutter is in the form of a tapered blade designed on the sole for producing an open cut or channel to accommodate the stitches.

The improved shield attachment is in the form of an elongated plate having a flat shank 18 bent up at 19 to provide a transverse shoulder 20 on the under side and continued therebeyond as shown at 21, parallel to the shank l8 and having a transverse slot 22 to receive the needle and the cutter, the plate being bent downward and tapered at its outer or free end at 23. The body has flanges 2% depending from its edges and producing a recess to inclose the needle plate let which usually overlies the table 10, and said body is also provided with an upstruck portion 25 to accommodate the set screw which holds the needle plate on the table. Said tapered portion 23 is provided with an inturned hook 26 which catches or fits under the needle plate. The opening or slot 22 also accommodates the needle and channel cutter and forms a shield which covers the channel cutter when it'is not desired to use the same, particularly when stitching rubber soles, thereby obviating the possibility of the rub ber catching in the cutter and interfering with the movement of the sole and the stitching operation.

At the opposite end of the shield, the shank portion 18 is preferably rounded as in- V dicated at 27 and provided with an aperture I provided a shield attachment for sole stitching machines which will effectively cover the channel cutter when stitching rubber soles on shoes and which will obviate the necessity of removing the channel cutter which usually requires the removal of its attaching screws and the application of a blank plate when stitching on rubber soles, thus saving considerable time and facilitating the work.

WVhile this attachment has been described as useful when stitching rubber soles on shoes, its use clearly is not confined to soles of rubber, nor to the soles of shoes, and I have found it serviceable for other uses as for instance in stitching light leather soles on ladies shoes which will not stand the use of the channel cutter.

What is claimed is:"

1. A shield attachment for shoe stitching machines comprising an elongated plate having an offset portion having side flanges and a rebent lip at the end thereof spaced from said flanges, said offset portion also having a transverse opening, said plate having an aperture adjacent its opposite end, a clamp having a tapered'lug and a shank turnably engaged in the aperture, a washer plate on the shank portion in contact with the plate and a lever on the shank portion.

2. A shield attachment for shoe stitching and channeling machines comprising a plate having an opening to accommodate the needle and cutter, one end portion of the plate having a terminal hook for engagement under the needle plate to hold the attachment against upward anovement therefrom, the attachment having at its opposite end, means for holding the said end portion against movement in all directions from the machine.

In testimony whereof, I affix my signature, in the presence of two witnesses.
